Chromatography and mass spectrometry


Gas chromatography–mass spectrometry (GC-MS) Liquid Chromatography-Mass Spectrometry (LC-MS) are used to identify different substances within a test sample. Applications of GC-MS and LC-MS includes drug detection, fire investigation, environmental analysis, explosives investigation, and identification of unknown samples. Most commonly used MS detector is the quadrupole mass spectrometer. Other detectors may be encountered such as time of flight (TOF), Orbitrap, tandem quadrupoles (MS-MS), or MSn where n indicates the number mass spectrometry stages.
